Post-Defecation Bleeding: When to Seek Medical Help - Surgery

Bleeding after bowel movements?


Hello Doctor: I sometimes experience constipation, having a bowel movement every two to three days, and occasionally I have abdominal pain followed by diarrhea.
Last night was particularly unusual; I was unable to have a bowel movement for about 20 minutes, which led to abdominal pain and even cold sweats.
After passing a hard stool, the subsequent stools were diarrhea.
I noticed blood on the toilet paper after wiping, and a few hours later, I felt some dull pain in my abdomen, with only blood in the stool, though the amount was small.
After a few more hours, the situation remained the same, but the amount of blood decreased.
I am concerned that there may be an issue with my intestines or stomach.
Two years ago, I underwent an endoscopy and tested positive for Helicobacter pylori, but I recovered after treatment.
Which specialty should I consult for my condition? Thank you, and Happy New Year!

Based on your description, it seems more like Irritable Bowel Syndrome (IBS).
It is recommended to start with a light diet and maintain a good lifestyle routine.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may consult a physician for medication.
If there is still no improvement, considering your age, it would be best to schedule a colonoscopy.

More Info


Understanding post-defecation bleeding can be concerning, especially when accompanied by symptoms like abdominal pain and changes in bowel habits. Based on your description, it seems you experienced a combination of constipation followed by diarrhea, which can sometimes lead to rectal bleeding. Let's break down the situation and discuss when it's necessary to seek medical help.


Possible Causes of Post-Defecation Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding, especially after straining during a bowel movement. Hemorrhoids can be internal or external and may cause pain, itching, and bleeding.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can be quite painful and may lead to bleeding.

3. Diverticular Disease: Diverticulosis can lead to diverticulitis, which may cause abdominal pain and bleeding. This condition is more common in older adults.

4. Gastrointestinal Conditions: Conditions such as inflammatory bowel disease (IBD), colorectal polyps, or even colorectal cancer can cause rectal bleeding, although these are less common.

5. Infections: Gastrointestinal infections can lead to diarrhea and sometimes cause bleeding, especially if there is significant inflammation.


When to Seek Medical Help
Given your symptoms, here are some guidelines on when to seek medical attention:
- Persistent Bleeding: If the bleeding continues or worsens over a few hours, it’s essential to seek medical help.

- Large Amounts of Blood: If you notice a significant amount of blood, especially if it’s bright red or dark, this warrants immediate medical evaluation.

- Severe Abdominal Pain: If the abdominal pain becomes severe or is accompanied by fever, chills, or vomiting, you should seek emergency care.

- Changes in Bowel Habits: If you experience significant changes in your bowel habits, such as prolonged diarrhea or constipation, it’s advisable to consult a healthcare provider.

- History of Gastrointestinal Issues: Given your previous history with H. pylori and gastrointestinal symptoms, it’s wise to consult a doctor if you have any concerns.


Recommended Medical Specialties
For your situation, the following specialties would be appropriate:
- Gastroenterology: This specialty focuses on the digestive system and its disorders. A gastroenterologist can evaluate your symptoms, perform necessary tests (like a colonoscopy if needed), and provide treatment options.

- General Surgery: If there are concerns about conditions like diverticulitis or if surgical intervention is necessary, a general surgeon may be involved.


Conclusion
In summary, while occasional rectal bleeding can be benign, especially if associated with hemorrhoids or anal fissures, it’s crucial to monitor your symptoms closely. Given your history and the nature of your symptoms, I recommend scheduling an appointment with a gastroenterologist for a thorough evaluation. They can provide a more accurate diagnosis and appropriate treatment plan.
Remember, it’s always better to err on the side of caution when it comes to gastrointestinal symptoms. Wishing you a speedy recovery and a happy new year!
